CALENDAR.

Application filed June as, 1912. Serial No. 7os,s27.-

To all whom it may concern:

Be it known that I, SAMUEL K. JENBIK,

-a--citizen of the United States, residing at act description. i

This invention is an improvement in calendars of the so-called perpetual type, in which, by the adjustment of certain movable parts, a calendar is provided which will correct-ly show any month of a large predetermined number of years.

The objects of my invention are to provide a calendar which shall have aminimum number of parts and which shall be capable of being'made of so small size and inconsiderable thickness as to be carried in the pocket or to be made as a part of the ordinary pocket memorandum book without mate? rially increasing the size of the book.

Other objects and advantages of my invention will later appear in the specification and be pointed out in the appended claims. To these ends my invention consists in the structure shown in the accompanying drawings in which,

Figure 1 is a plan or face view of my en'- tire device; Fig. 2 shows, on reduced scale, how the calendar may be folded to accommodate it to insertion into the pocket or into a book; Fig. 3 is a diagrammatic view showing the various thicknesses of material employed in building up the calendar; Fig. 4: is a plan view, on a reduced scale, of the element in which the tab bearing the numerals corresponding to the days of the month is adapted to slide; Fig. 5 is a. similar view of the element in which the month and year indicating disks revolve; and Fig. (3 is a perspective, on the same scale as Figs. 4 and 5, of the tab which carries the numerals corresponding to the days of the month, only two of these numerals, the ones which appear on a projection on the face of said tab, being shown.

The calendar consists essentially of a front or face member 7, which is twice the length of the remaining members, a rear or backing member 8, a rectangular-1y slotted member 9 directly hack of the face number, a partition 10, and a circularly recessed member 11 between the partition and rear member, together with the numeral carrying slide 12 and the month and year indicating disks [3 and 14. Inasmuch as the slide 12 and the disks 13 and 14 are embraced in the elements 9 and 11 they do not add to the thickness of the device and there are, when the face 7 is not folded up, but five thicknesses of material which, being made of paper, card-board, celluloid, thin metal or other suitable mate rial, may be comprised within a very inconsiderable thickness. A very material reduction in bulk is thus attained over those devices which include one or more endless belts traveling on rollers or similar suspending means. It will, of course, be understood that two or more of these parts may be perinanently secured together or maybe formed in one piece, and in fact I prefer to make the parts 9, 10 and 11 as a imit, but for purposes of explanation it is simpler to speak of them as though they were all detached and joined only on their edges' The face member 7 has a rectangular opening 15, and adjacent thereto, preferably above as shown, there is atable 16 of the days of the week. Openings 17 and 18 are also convenientl located in the face member 7 over the disks 13' and 14,, and I prefer to place these as shown directly above the table of the. days of the weekthough any other proper location with feference to the disks l3 and 14 will answer, Also on the face member 7 and below the opening 15 is located a table showing lhe'months in a vertical column and years in vertical and horizontal columns. The month eoiumn is just at one side of the vertical formii'ig one side of the opening ]:'i,'and the vertical year coluums, which are seven in number, are of the same width and directly under the spaces of the table 16 where are the \veek f 'l'lie numeral carrying slide 12 is divided into thirteen spaces in a horiz ntal direction and six spaces vertically. 'l'he numeral 1 appears in the middle space of the upper row and the rrliutllllllg spaces to the right are taken up by the numerals up to 7; the

second row reads from :2 to l-l; the third from 2) to it; the fourth from It? to 2-5; the fifth from 23 lo 3]; and the sixth from Sill to 31 as shown; the arrangement of the numerals and the size ol the opening l5 being such that there is alwaysrxposml in the opening 15 numerals reading from I to 31. A projecting portion H is provided on'dlie slide l2 b which the slide may be manipulated to place the numeral 1 over any desired vertical column of years. In

' this instance the projection is shown as being portion of the slide which is always exposed.

The operation of this part of my device is as follows: Given any desired month and year, to display the proper arrangement for that month of numerals on the slide .12 with relation to the days of the week as appearing in the table above: Look in the horizontal column in the lower table opposite the month in question until the desired year is found and then move the slide 12 unt1l the numeral 1 is over the year selected; the calendar for the month in-question will then be displayed in the opening 15, and the day of the week on which any particular date occurred may be determined by reference to table 16 above the slide.

As previously stated month indicating disks '13 and year indicating disks 14 are mounted in circular recesses 19 and 20 in the member 11 which is between the back 8 and the partition 10. Openings similar to 17 and 18 are provided in the partition'lO and these register with the said openings 17,

and 18 and these openings are of such size that the name of only one'month on 'the disk 13 or the figures representing one year only on the disk 14 will appear in said openings- If it is desired to use the device as an ordinary calendar the disks 13 and 14. may be turned to indicate the month and year'for which the calendar is set, though these parts are used only as indicators and do not form a part, of the-mechanism of the calendar proper, which. latter it will be evident -is capable of adjustment by a single operation-that of moving. the slide '12.

The slide 12 always shows numerals from 1 to 31 but the proper'number of days for any month may be readily determined by reference to the column of months where this information is given. Asterisks, or other similar indicating means may be added to the year columns to show which are leap years.

It will also be obvious that the table of years may be indefinitely enlarged at will to show any desired number of years, those chosen being merely given for purposes of illustration, or that the relative positions of the lower table and the table 16 maybe reversed; and that these and various other changes of arrangement-and so forth-may be made without departing from my invention.

Having thus described m invention, what I claim and desire to secure by Letters Patent is:

' 1.' In a calendar, a face member havinga plurality of openings therein, on'eof said openings being larger than the others, a week table on said face member, a slide havwhieh columns comprises a complete mensual calendar, said slide being adapted to move back of said face member, through the larger opening of which seven of its'columns are always exposed, an element embracing said slide and in which it',trave1s, a circularly recessed member, month and year indi- -cat1ng disks revolubly mounted in the recesses. oi said last mentioned element-in 'ing the days of the month thereon divided .into thirteen vertical columns, any seven of operative relation to the remaining openings 1n.said face member, and'a backing element. 2. In a "calendar,"a race member having a plurality of openings therein, one-of said openings being larger than the. others, a week table on said face member, a slide having the days of-the month thereon divided into thirteen vertical columns, any seven of which columns comprises a complete mensual calendar, said slide being adapted to move back of said face member, throu h the larger opening of which seven of its co uinns are always exposed, an element embracing said slide and in which it travels, a partition havingslots therein which register with the remaining openings in the face plate, a circularly recessed member back of said partition, month and year indicating disks revolubly mounted in therecesses of'said last mentioned element in operative relation to J. JEWELL, B. D. V. Rnnvn.
